Power factor correction integrated circuit
International Rectifier

International Rectifier, IR® (NYSE: IRF), a world leader in power management technology, today introduced the IR115x family of µPFC™ power factor correction (PFC) ICs for a wide variety of AC-DC applications including lighting, LCD/PDP TV and game console Switch Mode Power Supplies (SMPS), fans, air conditioners, and uninterruptible power supplies (UPS) ranging from 300W to 8kW.

The IR115x ICs, utilizing IR's One Cycle Control (OCC) technology, offer high power factor (PF), low total harmonic distortion (THD) and excellent DC Bus regulation while enabling drastic reduction in component count, PCB area and design time compared to traditional solutions. The ICs are designed to operate in continuous conduction mode Boost PFC converters with average current mode control over 85-264VAC input line voltage range.
